| Abstract: | Based on lanolin, maleic anhydride, mono-ethanolamine and Na2SO3, sulfonated and succinated lanolin fatliquor could be produced. The method is as following： Firstly, amidated lanolin could be obtained by means of chemical reaction between lanolin and monoethanolamine; Secondly, monoester could be produced by means of chemical reaction between amidated lanolin and maleic anhydride; Lastly, by means of sulfonation reaction, sulfonated and succinated lanolin leather fatliquor could be obtained from the monoester and Na2SO3. The optimum reaction conditions between lanolin and monoethanolamine are： reaction temperature 125 ℃, reaction time 3 h and catalyst （NaOCH3） 0.3% （based on mass fraction of lanolin）. The optimum reaction conditions between amidated lanolin and maleic anhydride are： 1：1.05 mole ratio of amidated lanolin to maleic anhydride, reaction temperature 90℃, reaction time 3 h. The optimum sulfonation reaction conditions are： 1：1.05 mole ratio of amidated lanolin maleic monoester to Na2SO3, reaction temperature 80℃ and reaction time 2 h. The acid resistant stability of the fatliquor is enhanced as the hydroxyl values of amidated lanolin increases. As the hydroxyl values of amidated lanolin is 119.07 mg KOH·g^-1, the fatliquoring leather has the best handle |
